NRay

Rendering Engine with Vulkan backend

Editor preview

The goal of this project is to build a foundation for research in high-performance computer graphics with aim on integrating neural networks into existing pipelines.

Features:

  1. Vulkan:

    • Fully automatic resource management with my helper library vulkan_backend
    • Support for GLSL, Slang and SPIR-V shaders
    • Bindless textures and buffers
    • Graphics pipeline library
    • MSAA

  2. Engine:

    • Physically-based rendering (PBR) with metallic-roughness pipeline
    • glTF 2.0 scene loading
    • Entity component system based on EnTT
    • Scene graph
    • Editor

Requirements

This project targets Vulkan 1.3 and C++20 with plans to remove headers entirely in favour of named modules and the C++23 std module. Currently it compiles successfully with recent releases of GCC, Clang and MSVC.

Dependencies:

Installation

  1. Clone the Repository:
git clone https://github.com/noir-nik/NRay.git
cd NRay
git submodule update --init --recursive
  1. Build the Project:
mkdir build
cd build
cmake ..
cmake --build . -j8
  1. Render a Scene:
./NRay <path-to-gltf>

You can inspect your scene using Maya-like controls.

Future plans:

  1. Ray Tracing: research of ray tracing acceleration methods including BVH traversal with machine learning.
  2. Differentiable rendering: optimization of materials and textures with the help of Slang automatic differentiation.
  3. Neural rendering of meshes and volumes and replacing PBR lighting functions with neural networks.
